Epocrates' launch of its application for the iPhone™ platform was the most successful in the company's recent history, with tens of thousands of new users in days and more than 10,000 new physician users in the first week. In just nine months since the app launch, more than 75,000 U.S. physicians have adopted the popular reference guide on their iPhones and iPod touch™ devices to help reduce medical errors, improve patient care and practice safer medicine.

The innovative iPhone OS platform allowed Epocrates to add new graphically-rich features to its applications, specifically, the Pill Picture and Pill Identification tools. With this enhanced functionality, clinicians can show their patients pictures of a newly prescribed drug, or identify a patient's existing medication with a physical description (e.g., round, blue and scored) when the name cannot be recalled.

Additionally, the premium Epocrates® Essentials suite leverages the iPhone's touch-screen interface to feature important drug, disease and diagnostic information that helps support a patient's consultation at the point-of-care from diagnosis to treatment. With this premium application, healthcare professionals can instantly access the following information at the touch of a finger:

• Drug prescribing and safety information for more than 3,300 drugs, including pill pictures
  
• Peer-reviewed disease content co-developed with the BMJ Group, publisher of the British Medical Journal, featuring evidenced-based treatment options and full-color disease images
  
• Infectious disease treatment guide with empiric and specific treatment recommendations
  
• Hundreds of diagnostic and laboratory tests for interpretation and diagnostic support
  
• 600+ alternative (herbal) medications with drug interactions
  
• MedMath medical calculators including commonly-used pregnancy wheel and unit conversions
